Abstract

An improved peak-to-average-power ratio reduction algorithm for discrete multitone systems is deduced by simultaneous optimization of the quadrature-amplitude-modulation constellation and the unused discrete multitone subsymbols. The proposed method is also applicable to multicarrier systems where all subchannels are active. Our simulations demonstrate that considerable performance improvement can be achieved over several existing methods at the cost of increased computational complexity.
